NEW YORK ( TheStreet) -- When investors are ready to sell at the drop of a hat; that's a clear sign you're in a bull market. Those were Jim Cramer's words to his "Mad Money" TV show viewers Wednesday. Cramer said today's selloff was not a market panic, but more of a selling squall that's a healthy part of any bull market.

Cramer explained that today's selloff, which came right after the best quarter the markets have seen in 14 years, is nothing to be afraid of. "You're nuts if you don't think investors will be taking profits," he said.

Sure, a Spanish bond auction didn't go well, admitted Cramer, and yes, the latest news out of the Federal Reserve signals that the markets are likely on their own from here. But Cramer reminded viewers not to be confused about who's really driving the markets. He said that Europe no longer has a strangle hold over U.S. markets and if the Fed isn't willing to help out the markets, then the U.S. economy must be even better than we expected.

Cramer said there are still many positives in the markets, including a resurgence in real estate and strong retail sales, as evidenced by Bed Bath & Beyond ( BBBY). All of these facts point to today's selloff being just a pause, said Cramer, and not a top in the markets.

Yes, oil prices are still high, noted Cramer, but this time it's due to real global demand and not rampant speculation. True, gold stocks are in decline, but that's only because they can't find enough gold to take advantage of record-high prices, he said.

Cramer concluded by saying that today's selloff was a classic sign of a bull market, something he's willing to celebrate instead of worry about.

Investors looking for a way to play on the wireless data explosion should look no further than SBA Communications ( SBAC), Cramer told viewers. With over 300 million wireless subscribers in the U.S. and new data-hungry devices like the iPad on the way, Cramer said the tower companies are among the least risky ways to play the wireless data revolution.

With the need for more wireless data growing by the day, Cramer said that wireless carriers only have two options, acquire more wireless spectrum from the FCC, or add more antennas to existing locations. Since wireless spectrum is a rare commodity, he said it's no wonder that wireless carriers like AT&T ( T) and Verizon ( VZ) are beginning to invest in infrastructure after a multi-year hiatus.

So why SBA over rivals American Tower ( AMT) and Crown Castle ( CCI)? Cramer said that both SBA and American Tower are superior to Crown Castle, but among the two, he likes SBA more because of its superior portfolio of towers and its growth potential.

Cramer said the economics at SBA are superb. The company operates 9,000 towers in the U.S., with another 1,500 in North and Central America. SBA also recently closed an acquisition that gives it thousands more locations, affording it even more operating leverage.

SBA recently closed a secondary offering of stock, noted Cramer, which is giving investors a rare opportunity to buy shares at a discount to where they would normally trade. He told viewers to use this weakness to buy in.

Off the Charts

Continuing with his "Off the Charts" segment from yesterday's show, Cramer outlined the fundamental reasons why he's bullish on both Intel ( INTC) and Microsoft ( MSFT). He said while these tech titans were the heart and soul of the PC revolution of the '80s and '90s, new product cycles are breathing new life into these all but forgotten companies.

Cramer said that Intel remains one of the dominant chipmakers on Earth, and while PC sales have been struggling, the company is now moving beyond the PC and is aligning itself with today's trends including mobile and cloud computing. Intel's server processors, for example, only account for 20% of Intel's sales, but the segment is growing three times faster than its PC business. The company is also aggressively pushing into the phone and tablet market with new, low-power chips.

Microsoft has always been a buy ahead of a new product cycle, said Cramer, and that's exactly where the company stands today ahead of its "Windows 8" launch later this year. Cramer said investors also underestimate the value of Microsoft's Xbox franchise, which has won the war in gaming consoles.

Cramer said of course he like Apple ( AAPL), a stock which he owns for his charitable trust Action Alerts PLUS, more than either of these two names, but with Intel and Microsoft paying a 3% and 2.5% dividend, respectively, "how can investors go wrong?
